Figures 7 and 8 are a selected series of originally acquired parasagittal sections, starting near the midline and proceeding laterally through the left side of the brain. Working off-campus? [20]:151 In comparison to other animals, the La Plata dolphin has an EQ of 1.67; the Ganges river dolphin of 1.55; the orca of 2.57; the bottlenose dolphin of 4.14; and the tucuxi dolphin of 4.56;[21] chimpanzees at 2.49; dogs at 1.17, cats at 1.00; and mice at 0.50. They are able to change their behavior radically to face new challenges, a hallmark of complex intelligence. [51], It was noted by ancient Romans and Asian elephant handlers (mahouts) that elephants can distinguish melodies. [77] Next, a treat was placed at the bottom of a bucket and, at the same time, the bucket was covered with a lid.

Large brains and cognition: Where do elephants fit in?. All Rights Reserved. The order Proboscidea emerged in the late Paleocene epoch, approximately 60 million years ago (Sukumar,2003).

In many animals, the brain is located in the head, usually closer to the primary sensory organs. Is Cetacean Intelligence Special? Human brain is more different than the brain of other animals. The telencephalon is similar in shape to those of the minke (Balaenoptera acutorostrata) (Igarashi and Kamiya,1972) and humpback (Megaptera novaeangliae) (Cozzi et al.,2001) whales, but is less compressed in the rostrocaudal axis than in the Delphinidae (Igarashi and Kamiya,1972; Marino et al.,2004). Images are 1.3 mm thick with a matrix size of 256 × 256 and in‐plane resolution of 32 × 32 cm, yielding a voxel size of 1.25 × 1.25 × 1.3 mm. Edward Thorndike argued that his cats and dogs escaped puzzle boxes through a mindless process of trial and error. Figures 4, 10, and 12 show the hippocampus, which is unusually large and surprisingly convoluted. Many investigators (Frahm et al.,1982; Allman,1998; Rilling and Insel,1999; Zhang and Sejnowski,2000; Bush and Allman,2003) have found that in mammals, neocortical white matter increases disproportionately with brain size. In fact, an important signaling center has been identified at the “cortical hem” adjacent to the hippocampal primordium in the developing mammalian telencephalon.

B: Cerebellum. Like several other species that are able to produce abstract art, elephants using their trunks to hold brushes create paintings which some have compared to the work of abstract expressionists. This investigation has revealed both similarities and differences between the elephant brain and the large brains of primates and cetaceans. The calf was observed to be weeping and made sounds that sounded like a scream, but then the entire herd fell silent. Calimero, an African elephant who was 23 years old, also exhibited a unique form of mimicry. To examine this possibility, we performed reduced major axis fits on the data set with and without the elephant.
